How to monetize international facebook traffic ?

Hello guys , how you all doing?

So i'm having those facebook pages i had on one dead accounts , they are like 200-300 small pages 1k to 20k each
and i was thinking as im doing nothing lately to start monetizing them a bit.. i use to be good in this sh*t but i have been out of IM for a few years..

So what do you recommend me ? to open a gallery script website with adsense? or go with my likes ? should i go something illegal , clickjacking or something?
I forgot to tell you that almost all the traffic its mixed up , international , serbia , albania, macedonia , mexico , argentina etc etc
so no us or target ones...

Thanks for your time

Starting with gallery and mylikes is good startup.
